DETAILED DESCRIPTION

The exemplary embodiments of the present application will be described below in combination with the drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as only exemplary. Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Likewise, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

According to a relationship between internal intention understanding and an external operation behavior by an intelligent voice device for a voice instruction in a man-machine interaction procedure, the embodiments of the present application proposes to serialize multi-round operation behaviors of the intelligent voice device in the man-machine interaction procedure, and evaluate a user's satisfaction with the intention understanding by the intelligent voice device based on a series of serialized data, which can reflect an intention understanding performance of the intelligent voice device for a voice instruction.

On this basis, FIG. 1 is a flow block diagram showing a method for generating a user intention understanding satisfaction evaluation model according to an embodiment of the present application, the method including:

S101, acquiring a plurality of sets of intention understanding data, at least one set of which includes a plurality of sequences corresponding to multi-round behaviors of an intelligent device in multi-round man-machine interactions; and

S102, learning the plurality of sets of intention understanding data through a first machine learning model, to obtain the user intention understanding satisfaction evaluation model after the learning, wherein the user intention understanding satisfaction evaluation model is configured to evaluate user intention understanding satisfactions of the intelligent device in the multi-round man-machine interactions according to the plurality of sequences corresponding to the multi-round man-machine interactions.

According to the embodiment of the present application, firstly a plurality of sets of intention understanding data is acquired, which may be data collected for one intelligent device or a plurality of intelligent devices. Each set of data includes a plurality of sequences corresponding to multi-round man-machine interactions, wherein one sequence corresponds to a behavior of the intelligent device in one round of man-machine interaction. Here, since the behavior of the intelligent device is an operation behavior after the intention understanding of a voice instruction by the intelligent device, the behaviors of the intelligent device are serialized so that the intention understanding by the intelligent device is abstracted into analyzable data, which is prepared for a next step of training a machine learning model.

According to the embodiment of the present application, a machine learning model is used to learn a plurality of sets of intention understanding data, to determine a model parameter, thereby constructing a model capable of evaluating a user intention understanding satisfaction of the intelligent device, and an evaluation result can reflect an intention understanding ability of the intelligent device, and can be applied to the fields of intelligent voice recognition and knowledge graphs.

In the embodiment of the present application, optionally, multi-round man-machine interactions corresponding to a plurality of sequences in a same set of intention understanding data should be continuous. Data of the multi-round continuous man-machine interactions can be used to truly reflect a relationship between operation behaviors occurring during the interaction between the user and the intelligent device.

For example, in a case where the user issues a same instruction for a plurality of times in succession, it may be considered that the intelligent device has an incorrect intention understanding of the instruction, and the feedback information does not meet the user's need, which causes the user to issue the same instruction again and again. At this time, the user intention understanding satisfaction of the intelligent device is determined to be unsatisfied or inaccurate, or other similar expressions.

In the embodiment of the present application, optionally, the plurality of sequences include a first sequence corresponding to a behavior category, to which a first behavior of the intelligent device belongs. Similarly, a second sequence in the plurality of sequences corresponds to a behavior category, to which a second behavior of the intelligent device belongs, and the rest of the sequences are deduced by analogy.

In the embodiment of the present application, the behaviors of the intelligent device may be serialized based on reasonable classification of various operation behaviors of the intelligent device. For example, according to attributes of the instructions that can be recognized by the intelligent device, or attributes of the operation behaviors of the intelligent device, the operation behaviors may be classified into a control category (001), an audio-visual category (002), a game category (003), an information category (004), an education category (005), a leisure category (006), a home control category (007), etc., wherein a bracketed number is a serial number for a category.

In the embodiment of the present application, the behavior categories and the serial numbers should be in a one-to-one corresponding relationship. The specific format and value of the serial number may be set as needed, and there is no special limitation in the embodiment of the present application.

In the embodiment of the present application, if a first-round behavior in the multi-round behaviors belongs to a first behavior category, the first-round behavior is labeled as the first sequence; and if a second-round behavior in the multi-round behaviors belongs to a second behavior category, the second-round behavior is labeled as the second sequence.

In this way, each operation behavior of the intelligent device may be classified in a set classification manner, and a serial number thereof may be determined. For example,

“Play a song” is an operation behavior of the audio-visual category, with a serial number of 002;

“Volume up” is an operation behavior of the control category, with a serial number of 001;

“Broadcast destination weather” is an operation behavior of the information category, with a serial number of 004;

“Play course training video” is an operation behavior of the audio-visual category or the education category, with a serial number of 002 or 005.

In the embodiment of the present application, further, the operation behaviors of the intelligent device may be classified in levels, so that the classification is more refined and accurate, a granularity of the evaluation is reduced, and the evaluation result is more accurate.

In one embodiment, the plurality of sequences include a second sequence, which includes a first subsequence and a second subsequence, wherein the first subsequence corresponds to a first-level behavior category, to which a second behavior of the intelligent device belongs, and the second subsequence corresponds to a second-level behavior category, to which the second behavior of the intelligent device belongs, and wherein one first-level behavior category includes one or more second-level behavior categories.

In the embodiment of the present application, the classification manner described above may be regarded as a first-level classification, and on this basis, each operation category in the first-level classification may be subdivided into second-level classifications.

Illustratively, specific examples are given below for description.

-   -   The first-level classification may include the following         categories:

a control category (001), an audio-visual category (002), a game category (003), an information category (004), an education category (005), a leisure category (006), a home control category (007), etc.

-   -   The second-level classification subdivides the categories in the         first-level classification as follows:

1) the control category (001) in the first-level classification may be subdivided into: volume up (0001), volume down (0002), exit application (0003), shut down (0004), basic settings (0005), wake up (0006), etc.;

2) the audio-visual category (002) in the first-level classification may be subdivided into: song playback (0001), video playback (0002), playlist (0003), progress adjustment (0004), change the song (0005), song information (0006), singer information (0007), play video (0008), video information (0009), play completed (0010), etc.:

3) the information category (004) in the first-level classification may be subdivided into: weather check (0001), play completed (0002), etc.

Those bracketed in the above example are serial numbers corresponding to various categories. A serial number of the first-level classification and a serial number of the second-level classification may be superimposed as a serial number of a specific operation behavior.

In practical applications, suitable first-level classification and second-level classification may be set according to the evaluation need and the characteristics of the intelligent device per se, and they are not exhaustive in the above examples.

Based on the above multi-level classification principle, serializing the information of the multi-round behaviors in the embodiment of the present application may include the following steps:

if a first-round behavior in the multi-round behaviors belongs to a first behavior category in a first-level behavior category set and also belongs to a second behavior category in a second-level behavior category set, labeling the first-round behavior as a superimposed sequence of a first sequence and a second sequence, wherein the first sequence and the second sequence correspond to the first behavior category and the second behavior category, respectively;

if a second-round behavior in the multi-round behaviors belongs to a third behavior category in the first-level behavior category set and also belongs to a fourth behavior category in the second-level behavior category set, labeling the second-round behavior as a superimposed sequence of a third sequence and a fourth sequence, wherein the third sequence and the fourth sequence correspond to the third behavior category and the fourth behavior category, respectively.

In order to more clearly explain a relationship between a code of a control behavior sequence of the intelligent device and a user intention understanding satisfaction in the embodiment of the present application, a specific example is given as follows to describe a procedure of multi-round human-machine interactions between a user and an intelligent speaker.

In the procedure of multi-round human-machine interactions, the user issues a voice instruction to the intelligent speaker, which performs intension understanding on the voice instruction after recognizing the voice instruction, and makes an answer feedback and a corresponding operation behavior according to the intension understanding.

Specifically, the answering procedure of the instruction of the user and the intelligent speakers includes:

Instruction 1: Xiaodu Xiaodu;

Answer 1: I am here; (0010006)

Instruction 2: Play Jay Chou's songs;

Answer 2: Okay, I will play “Fragrant miles and miles”; (0020001, 0020010) and “Confession Balloon”; (0020001)

Instruction 3: Next song;

Answer 3: Okay, I will play “Listen To Mother's Words”; (0020005)

Instruction 4: The voice would better be higher;

Answer 4: Volume up; (0010001)

Instruction 5: Weather in Beihai;

Answer 5: Weather in Shanghai is; (0040001) [an error of intention understanding occurs]

Instruction 6: Weather in Beihai, Guangxi Zhuang Autonomous Region;

Answer 6: Weather in Beihai; (0040001, 0040002)

Instruction 7: Exit;

Answer 7: Exit. (0010003)

For the convenience of description, sequences of the operation behaviors of the intelligent speaker have been listed in corresponding brackets. For example, Answer 1 is “I am here”, wherein this operation behavior is that the device is waked up, which corresponds to “control category (001)” in the first-level classification and “wake up (0006)” in the second-level classification. Thus, a sequence corresponding to the behavior “I am here” in Answer 1 is 0010006, and a code of this sequence is a superposition of the serial number of the first-level classification and the serial number of the second-level classification. In addition, the intelligent speaker is successfully waked up, and a result of the intention understanding of the instruction is “satisfied”.

It should be noted that for Answer 5, the intention of Instruction 5 is to check the weather in Beihai, while Answer 5 broadcasts the weather in Shanghai (in fact, an error of intention understanding of Instruction 5 occurs). At this time, the user interrupts the broadcast of the weather in Shanghai, issues Instruction 6 that is intended to check the weather in Beihai, Guangxi Zhuang Autonomous Region. It can be seen that Instruction 6 is actually a repetition of Instruction 5, and Answer 7 of the intelligent speaker broadcasts the weather in Beihai. In addition, this broadcast is completed without being interrupted, and the intension understanding is correct.

As can be seen from the above two interactions, Answer 6 and Answer 5 both broadcast the weather, so the sequences of the two operation behaviors both have 0040001; further, Answer 6 completes the broadcast, and corresponding sequence is added with 0040002, while Answer 5 does not complete the broadcast, and there is no corresponding sequence. From the analysis of the two answering behaviors, it can be concluded that the intelligent device understands the intention of Instruction 5 incorrectly, and the user is not satisfied, while the intention of Instruction 6 is correctly understood, and the user is satisfied.

Therefore, from the above multi-round human-computer interactions, a plurality of operation behavior sequences (denoted as o_(i)) and the corresponding user intention understanding satisfactions (denoted as it) may be obtained as follows:

0010006 (satisfied), 0020001 (satisfied), 0020010 (satisfied), 0020001 (satisfied), 0020005 (satisfied), 0010001 (satisfied), 0040001 (unsatisfied), 0040001 (satisfied), 0040002 (satisfied), 0010003 (satisfied).

In the embodiment of the present application, optionally, a large number of operation behavior sequences and corresponding user intention understanding satisfactions are taken as training sample data to train a neural network, such as a convolutional neural network or a recurrent neural network, so as to obtain a user intention understanding satisfaction evaluation model, which can applied to the fields of intelligent voice recognition and knowledge graphs.

In the embodiment of the present application, optionally, a Hidden Markov Model (HMM) may also be taken as a machine learning model to be trained or learned. Optionally, based on the aforementioned operation behavior sequences and the corresponding user intention understanding satisfactions, a model parameter is learned in a supervised learning manner to generate the user intention understanding satisfaction evaluation model. Optionally, the user intention understanding satisfaction evaluation model may also be generated by learning the model parameter in an unsupervised learning manner based only on the aforementioned operation behavior sequences.

On this basis, a method for evaluating a user intention understanding satisfaction is also provided according to an embodiment of the present application, the method including:

S201, acquiring information of multi-round behaviors of an intelligent device in multi-round man-machine interactions to be evaluated;

S202, serializing the information of the multi-round behaviors, to obtain a plurality of sequences; and

S203, inputting the plurality of sequences into a user intention understanding satisfaction evaluation model, to obtain evaluation results of user intention understanding satisfactions to be outputted by the model, wherein the user intention understanding satisfaction evaluation model is configured to evaluate the user intention understanding satisfactions of the intelligent device in the multi-round human-computer interactions according to the plurality of sequences corresponding to the multi-round human-computer interactions.

Through the embodiments of the present application, the evaluation of the user intention understanding satisfactions of the intelligent device can be realized based on the behavior sequences of the intelligent device during the multi-round man-machine interactions.

For example, when it is necessary to evaluate the performance of a certain intelligent device, such as the ability of intension understanding, an operator may acquire information of a series of operation behaviors during multi-round human-computer interactions with the intelligent device, and perform serialization thereof, for example, perform classification and serialization according to the classification principle provided in the embodiments of the present application, and input results into the user intention understanding satisfaction evaluation model to obtain evaluation results of the user intention understanding satisfactions of the multi-round human-computer interactions. The evaluation results may be a series of satisfaction states, and the ability of intension understanding of the intelligent device improves as the number of “satisfied” increases.

In the embodiment of the present application, as described above, a Hidden Markov Model may be constructed based on the operation sequences for the intension understanding, because first of all, supposing that the operation sequences of the user satisfy the Markov property and the observation independence assumption, that is, the state variable sequences are arranged in a chronological order, and the distribution characteristics at a moment N+1 are related to the distribution at a moment N, regardless of the value of the variable before the moment N. The plurality of operation behavior sequences in the embodiment of the present application are denoted as o_(i), the user intention understanding satisfactions are denoted as i_(t), and P(i_(t)|i_(t−1), o_(t−1), . . . , i_(l), o₁)=P(i_(t)|i_(t−1)), t=1, 2, . . . , T, wherein P represents a probability. Regarding the observation independence assumption, the observation at any moment depends only on the state of the Markov chain at that moment, regardless of any other observation or state, i.e., P(o_(t)|i_(T), o_(T), . . . , i_(t+1), o_(t+1), i_(t), i_(t−1), o_(t−1) . . . , i₁, o₁)=P(o_(t)|i_(t)).

In the embodiment of the present application, if it is supposed that the operation sequences of the user are Markovian, it means that a current operation behavior is probabilistically related to an operation behavior of a previous step, regardless of any other previous operation behavior. For example, in the above example of the multi-round human-computer interactions, the user wants to obtain the weather in Beihai, while the intelligent device broadcasts the weather in Shanghai. The user's behavior at that time is to interrupt the broadcast of the weather in Shanghai and reinitiate a question. The behavior of reinitiating the question has nothing to do with the previous operations such as listening to a song. The parameter values of the Hidden Markov Model Δ=(A,B,π) may be estimated based on a given user set U={u₁, u₂, u₃, u₄, . . . u_(n)} and the operation sequence O_(i) of each user, wherein A represents a state transition probability matrix, B represents an observation probability matrix, and c represents an initial state probability vector. A maximum likelihood estimation method may be adopted to maximize the observation sequence probability P(O|λ) under this model, so as to obtain the learned parameter values.

In the embodiment of the present application, the model parameter values may be learnt using a supervised learning method or an unsupervised learning method. On the one hand, when using the supervised learning method, it is necessary to label a state sequence (i.e., a satisfaction sequence) corresponding to the user's operation sequence, and then estimate the parameter values of the Hidden Markov Model using the maximum likelihood estimation method. On the other hand, a Baum-Welch algorithm (EM algorithm), i.e., the unsupervised learning algorithm, maybe used for unsupervised learning to obtain the constructed Hidden Markov Model.

In the evaluation, the user intention satisfaction evaluation is performed based on the constructed Hidden Markov Model. Since the Hidden Markov Model λ=(A,B,π) and the operation sequence O_(i)=(o₁, o₂, . . . o_(T)) of the intelligent device have been known, a Viterbi algorithm is adopted to solve a path of a maximum probability through dynamic planning, so as to obtain a sequence I_(i)=(i₁, i₂ . . . i_(T)) in a state with a maximum conditional probability P(I|O) of the given operation sequence, wherein nodes on the path each correspond to a satisfied or unsatisfied state, thereby obtaining the satisfaction sequence corresponding to the operation sequence, i.e., the evaluation result of the user intention understanding satisfaction of the intelligent device.

According to the embodiments of the present application, the behaviors of the intelligent device are serialized, so that the intention understanding by the intelligent device is converted into analyzable data, to enable a suitable machine learning model to be constructed, to realize the evaluation of the user intention understanding satisfaction.
